Description of the invention (6) Detailed description of the embodiment Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) Figure 3 is a special embodiment of the rear derailleur shock absorber device according to the present invention Detailed view. In this embodiment, a bicycle derailleur (200) for attaching to a bicycle frame (204) includes a base member device (208) that includes a first projection (210) in the form of a positioning member or a stop wall. ), The base member (209), and the connecting member (2 1 2), which can be a threaded shaft or other components as discussed in the above conventional technology, for connecting the base member device (208) to the bicycle frame (204) ). A chain guide (not shown) is connected to the base member device (2 0 8-1) via a connecting rod (220, 224), and resists the force of the return spring (2 0 9) relative to the base member device (2 0 8 ) Move and guide the chain (not shown) between multiple sprockets (not shown) in a known manner. When the base device (2 0 8) is mounted on a bicycle, the first protruding portion (2 1 0) may be opposite to the second member (2 3 4) formed on the first protruding portion (2 1 0). The second protrusion (2 3 0) on the upper part rotates. This rotation can occur intentionally as part of the design, or it can occur due to the force applied to the derailleur during the severe operation of the bicycle. • * The shock absorber (2 40) is disposed between the first protruding portion (2 1 0) and the second protruding portion (2 3 0), and is used to absorb the first protruding portion (2 1 0) and the first protruding portion (2 1 0). Steep earthquake between two protrusions (230). More specifically, in this embodiment, the adjustment screw (2 50) is screwed into the first protrusion (2 1 0), and the shock absorber (240) is provided between the adjustment screw (2 50) and the second Between the protrusions (230), but in other implementations of this paper size, the Chinese National Standard (CNS) A4 specification (210X297 mm) A7 _B7_ V. Description of the invention (7) In the example, the adjusting screw (2 50), and for example, the shock absorber (240) can be directly attached to the first protrusion (21 0) and the second protrusion by bonding the shock absorber (240) to the first protrusion (2 1 0). Department (2 3 0). The shock absorber (240) can be made of rubber, soft plastic, elastomer, compression spring, or other compressible or elastic members that can absorb steep shocks. The same is true for the embodiments described below. Fig. 4 is a detailed view of another embodiment of a rear derailleur, shock absorber device according to the present invention. The shock absorber device according to this embodiment can be used for a derailleur constructed in accordance with the teachings of the above-mentioned US Patent No. 4,690,663 described with reference to Figs. 1 and 2, and therefore are denoted by the same reference numerals The same components. In this embodiment, the shock absorber (300) is disposed between the adjustment screw (108) and the abutment surface (104). If desired, the shock absorber (300) can be applied to a derailleur constructed according to the teachings of U.S. Patent No. 4,6 1 0,6 4 4 in which the adjusting screw (1 0 8) is omitted, and For example, by attaching the shock absorber (300) to the positioning nose (110), the shock absorber is directly disposed between the positioning nose (110) and the abutting surface (104). Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative (please read the notes on the back before filling out this page). Figure 5 shows another implementation of the rear derailleur shock absorber device according to the present invention. • Detailed view of the casting example. The shock absorber device according to this embodiment can also be used for a derailleur constructed in accordance with the teachings of U.S. Patent No. 4'690'663 as indicated above and described with reference to Figs. 1 and 2, and therefore the same reference numerals are used to denote the same Of components. In this embodiment, the base member stopper (82) in FIG. 2 is modified into a shape having a bumper supporting protrusion or abutment surface (82 '), so that the bumper (320) can be set In this paper scale, the Chinese National Standard (CNS) A4 specification (.210X297 mm) -10- A7 B7__ V. Description of the invention (8) The shock absorber support projection (82 ') and the positioning member (91) Positioning plate stopper (94). By omitting the adjustment screw (108) 'the same design can be used for a derailleur constructed in accordance with the teachings of U.S. Patent No. 4' 6 1 0 '6 4 4. Fig. 6 is a detailed view of another embodiment of the rear derailleur shock absorber device according to the present invention. The shock absorber device according to this embodiment can also be used for a derailleur constructed according to the teachings of the above-mentioned US Patent No. 4,690,663 as described with reference to Figs. 1 and 2, and therefore use the same reference numerals. Denotes the same component. In this embodiment, the adjusting screw (108) is not screwed into the positioning nose (92). In contrast, the positioning nose (9 2 ′ Γ is configured similar to the positioning nose disclosed in US Patent No. 4,6 1 0,644, and the base member stopper (8 2) in FIG. 2 is Modified to have the shape of the shock absorber support protrusion or abutment surface (8 2 ") that accommodates the adjustment screw (108), so that the shock absorber (3 70) can be placed on the adjustment screw (108) and positioned Printed by the plate stopper (94). Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). It can be adopted under the spirit and scope of the invention. For example, the size, shape, position, or orientation of various components can be changed as desired. The function of one element can be implemented by two elements, and vice versa. A shock absorber is used to absorb the steep shock when the base member device (1 4) rotates counterclockwise as shown in FIG. 1, but the derailleur can be constructed when the base member device (1 4) rotates clockwise Absorbs shocks. As mentioned above, the abutment surface can be formed at The abutment surface on the traveling frame can be used when the derailleur is installed on this paper, and the Chinese national standard (CNS) A4 specification (210X297 mm) is applied. -11-A7 B7 V. Description of the invention (9) The abutment surface formed by a separate member attached to the derailleur and fixed relative to the frame, or any other member that can function in a similar manner. Therefore, the scope of the present invention should not be limited by the specific structure disclosed. The scope of the invention should be determined by the scope of patent application.
